Hi,
I don't receive many "Dead On Arrival"(DOA) units to start with. The problem is, that there is a limit for the Kama Meter to deal with fans. If you overload it with too much wattage consumption of fans, it might just die. I never had a Kama Meter die on me, and I ran 4 fans at the same time already, nothing happened, everything worked well. Could you tell me the exact name and model number of the used fans? I would like to find out the reason for it and make sure you won't have another dead unit
